Get basic lifecycle example running in qnx_qemu

[NicolasFussberger]

Get a lifecycle example running in qnx_qemu.

Basic Scenario:

• Launch Manager is started
• Launch Manager starts a demo application, that reports Running state and reports alive notification cyclically
• Alive supervision within launch manager is successful
• After couple of seconds, Launch Manager gets terminated by sending SIGTERM signal

Ongoing Problems:

• qnx_qemu uses old dependencies
  • Workaround: Created a branch in lifecycle repo with the same old baselibs version
• Could not use the latest lifecycle main branch, as there were some problem with rust toolchain when using it within qnx_qemu
  • Workaround: Uses an older version of lifecycle repo, which is working fine
• The itf ssh command does not support long-running processes, but expects processes to terminate quickly
  • Workaround: Use a shell command that starts launch_manager in the background, sleeps few seconds, then sends SIGTERM
• The itf ssh command is not working with complex command (e.g. using (,),&&,; ...) as the command itself is inserted into some complex sh command.
  • Workaround: Put the shell command into a dedicated script, so I only need to invoke a script via ssh

Running the test:
bazel test --config=qemu-integration //:test_lifecycle_qemu --test_output=all
